A total 24 patients consist of the study population. These 24 patients are prospectively divided into the CS-CPB group and OS-CPB group in double blind fashion. Then, the patients will undergo cardiac valve surgery using either open system or closed system cardiopulmonary bypass. Blood collection is performed at four time points, before starting CPB, immediately after surgery, and 24 and 48 hours after surgery. In each time point, the following data are measured; white blood cell, hemoglobin, hematocrit, platelet, serum creatinine, serum AST, serum ALT. Length of postoperative mechanical ventilation, ICU stay, occurrence of AKI, and intraoperative bleeding are investigated in each group.
